the staghorn is one of the cva's that can be converted to #11 by just changing breech plug (according to cva's website). so even if that gun is a 209, a call to cva and probably 20$ for a breech plug would fix it. The staghorn is an open breech design. the only problem when i had mine was cheap plastic sights, but i think better sights are available for 30$ or so. for the price they are very accurate.
